On the distribution of concentrations in emanation and hydrochemical halos

Abstract

Some geological formations with increased radioactivity, due to the release of emanations in them, create emanation halos around themselves. The main mechanisms of scattering in this case are diffusion and convection. The use of radioactive search methods requires studying the concentration distribution in such halos. For the case of emanation propagation in loose sediments covering an infinite radioactive half-space, there are methods for calculating the concentration under the combined action of diffusion and convection and separately. For local objects such as veins, strata extending beneath sediments, there is only the theory of Diffusion halos developed by Yu.P.Bulashevich.
